If you are not overriding +automaticallyNotifiesObserversForKey:, then why are you manually sending -willChangeValueForKey: and -didChangeValueForKey:? You are already benefitting from automatic KVO support (assuming your accessor is named -interpolationMode). -willChangeValueForKey: and -didChangeValueForKey: are only for manual KVO support, which requires overriding +automaticallyNotifiesObserversForKey: to return NO for the key in question: http://developer.apple.com/documentation/Cocoa/Conceptual/KeyValueObserving/Concepts/AutoVsManual.html#//apple_ref/doc/uid/20001844-178876 >> sending +setKeys:triggerChangeNotificationsForDependentKey: anywhere? > > Yes, for a couple of other controller keys that are dependent on the one > above. > They get set in my controller's +initialize method. The reason I ask these questions is so that by examining your code, we may figure out what's going wrong. The crucial step in this process is the posting of code. ;-) --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
